The third refers to the great quantity of pure air contained in the calces of metals.
Calces of cobalt and of copper differ very materially from those above mentioned in their application for colouring enamels.
Priestley's discovery of procuring pure air in such great abundance from the calces of metals.
One part of either of these calces is put to ten, sixteen, or twenty parts of the flux, according to the depth of colour required.
It may be resuscitated, like the calces of Antimony, into a Regulus, by re-uniting it with a phlogiston.
Fat Oils dissolve not only Lead, but its calces also: nay, they dissolve the latter more readily than Lead in substance; probably because they are more divided.
All the calces of Antimony, when exposed to a violent fire, are converted into Glass; but not all with the same facility.
Of all the metalline calces that of Antimony is most easily reduced.
To combine Fat Oils with Lead, and the Calces of Lead.
These calces are capable of uniting with phlogiston in indefinite proportions.
Thus quicklime possessed properties very similar to the calcesof metals.
And it was known that when the other calces were heated with charcoal, they were reduced to the metallic state, and at the same time carbonic acid gas is evolved.
Lavoisier showed that the sulphur, phosphorus, charcoal, and metals, were simple substances; and that the acids or calces formed were compounds of these simple bodies and oxygen.
Hence the inference was obvious that carbonic acid is a compound of charcoal and oxygen, and therefore that all calces are compounds of their respective metals and oxygen.
Besides, he had ascertained by direct experiment, that the calces of mercury, tin, and lead are compounds of the respective metals and oxygen.
It was the opinion at that time, that metals were compounds of their respective calces and phlogiston.
On the other hand, when calces are reduced to the metallic state hydrogen is absorbed.
He observes that when the metallic calces are reduced to the metallic state it is found necessary to heat them along with charcoal.
The calces of metals are those bodies deprived of phlogiston.
In the 4th and 5th chapters he proves that when metallic calces are reduced, by heating them with charcoal, an elastic fluid is evolved, precisely of the same nature with carbonic acid gas.
The very same evolution takes place when calces of mercury, tin, and lead, are heated with charcoal powder.
Its calces are white when imperfect, but black, or dark green, when perfect.
Calces of metals heated in inflammable air are revived, and the air absorbed; and since all the metals are revived in the same inflammable air, the principle of metallization, or phlogiston, appears to be the same in them all.
That the calces of metals contain air, of some kind or other, and that this air contributes to the additional weight of the calces, above that of the metals from which they are made, had been observed by Dr.
The fixed air thus precipitated from common air by means of phlogiston unites with lime, if any lime water be ready to receive it, unless there be some other substance at hand, with which it has a greater affinity, as the calces of metals.
The rust of iron, and the precipitate of nitrous air made from copper, also imbibed this air very fast, and the little that remained of it was inflammable air; which proves, that these calces contain phlogiston.
Of his chemical discoveries made after leaving England, the most important was that an inflammable gas is obtained by heating metallic calces with carbon.
Now they triumphantly asked, Why, when metals dissolve in diluted vitriolic or muriatic acid with evolution of inflammable air, are calces of these metals produced?
The upholders of the theory of phlogiston laid considerable stress on the fact that metals are produced by heating metallic calces in inflammable air; the air is absorbed, they said, and so the metal is reproduced.
Fire-Ochres Slags, volatilized calces of the difficultly fusible metals, as oxyde of or White antimony, Protoxide of Arsenic.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "calces" in a variety of sentences. We hope that you will now be able to make sentences using this word.
